FOR YOUR CONVERSATION WITH FAS
Your observation notes.
Stair-step cracks in brick or block
Note which wall has the crack and whether it follows the joints between blocks or bricks.
Ask FAS: What should be checked around this wall and the ground beside it?
Cracks across tile or slab floors
Photograph the full route of the crack, including where it crosses into another room.
Ask FAS: Is the visible crack in the floor finish, the slab beneath it, or both?
A visibly wide or open crack
Include a ruler in a clear photo and record the location. The drawing exaggerates width to make it visible.
Ask FAS: What measurements would help you assess this opening?
A crack that has changed over time
Compare dated photos of the same spot. Note when you first noticed a change.
Ask FAS: What can the timing and pattern of this change tell you?
Doors or windows that stick
Record which openings stick, whether they latch, and when you first noticed it.
Ask FAS: What should be checked to understand why this opening no longer works smoothly?
Sloping or bouncy floors
Note where the floor feels uneven or moves underfoot, and whether the home has raised floors.
Ask FAS: What would you inspect beneath or around this part of the floor?
Gaps where walls meet floors or ceilings
Photograph the joint and enough of the room to show its location.
Ask FAS: What measurements and nearby details would help explain this gap?
Cracks at door or window corners
Capture the whole opening and a close-up of the crack. Note any similar cracks nearby.
Ask FAS: What other observations should be compared with this crack?
